Another possible solution.
We have 5 windows logons in each room (myself, for 2 residents, front desk and MA). If one of the other persons, say one of the residents is not there I can go into their windows logon, CTRL-L will change the AC back to the logon screen and logon as myself. Then WINDOWS-L will return me to the logon screen where I can switch back to my logon and work on a different patient.
I then have to switch back and forth with WINDOWS-L between the logons to work with multiple patients. I need to check at the end of the day that I neither left an unfinished note (because I don't frequently log on as a resident) nor left it signed in under me and the resident then comes in another day and charts under my name (I would not have opportunity to review).
Clunky but it works
